INSTRUMENTATION
ON/OFF Switch
The dryer is equipped with an ON/OFF switch on the front
panel. A light signals when the dryer is on.
CONDENSATE DRAIN VALVES
A float operated drain is housed in a metal bowl. It will
automatically drain the condensate.
START-UP/OPERATION
Follow the procedure below to start your dryer. Failure
to follow the prescribed start-up procedure will invalidate
the warranty. If problems arise during start-up, call your
distributor.
Refer to Serial Number Tag for dryer
operating capacity. Do not exceed recommended capacity.
Drain connections must be made before the dryer can be
operated. The dryers are fully automatic and require no
auxiliary controls.
1. Connect inlet and outlet lines to the dryer. Reference
dryer indentations and instruction tag for appropriate
inlet and outlet connections.
2. Route drain connections to a condensate separator or
approved collection point.
3. Turn the on/off switch to on. Double check
connections.
4. After the dryer has been running for 30 minutes:
a. Check that on/off lighted switch is glowing. If
light is not glowing, unplug unit and refer to Field
Service Guide for additional information or call
your local distributor.
b. Confirm that condensate is discharging from the
drain. This can only be done when there is air flow
through the dryer.
Reference Serial Number Tag for
appropriate power requirement/connection rating. Make
other dryer connections prior to connecting power
source.
The dryer is designed to run continuously. Let the
dryer run even when the demand for compressed air is
interrupted; the dryer will not freeze up.
Operating Check Points
1. Power light is on, light is illuminated.
2. Condensate is discharging properly.
SHUTDOWN
When the dryer must be shutdown for maintenance or
other reasons, use the following procedure:
1. Turn the power on/off switch to off.
2. Disconnect the main power supply.
If mechanical repairs are to be made or service is
performed, vent the internal pressure of the dryer to
atmospheric pressure. Restart the dryer according to the
start-up instructions.
Disconnect power supply and depressurize
dryer before servicing. Dismantling or working on any
component of the compressed air system under pressure
may cause equipment failure and serious personal injury.
